Effective wetting dispersants for dispersing fillers in epoxy resin.
Mechanism of action of wetting dispersants and the resulting effects. By using a de-agglomeration type wetting dispersant to widen the distance between fillers, thixotropy is weakened and approaches Newtonian viscosity, resulting in a significant reduction in viscosity, especially at low shear rates.
